Petrology and structural studies in liquefaction reactions of Late Permian coals from Southern China

- The liquefaction behavior of the samples having high hydrogen was studied.
- Some of the inertinites underwent liquefaction reaction for DHB.
- Barkinite reacted in liquefaction.
- The chemical structural change during liquefaction was studied by FTIR, Py-GC/MS.
- C2-naphthalene and C3-naphthalene become the main constitutions in the residues.
